They aren't lying when they say immediate support. I receive responses WITHIN 5 minutes, as that's how often my browser refreshes. They are experienced and knowledgeable, and can help you with nearly all issues or errors you're having. It's also a huge plus that they give free web hosting. Upon buying a server, you can expect it to be up and fully functional within minutes, and everything is immediately setup. An online RCON tool is also a plus, as you can remotely control your server even if you're not connected. A high-speed FTP server is also included in the plan, for both the Game server and Web server.

If you were debating a server hosting service, DEFINITELY pick NFO. They actually care about their customers, and if you need help they will be glad to help.
